Once a man saw a strange dream. He couldn't understand meaning of his dream. So, one day he decided to visit holy man to ask him about his dream. Next day, he came to holy man and told him, "I had a very strange dream. I couldn't understand it's meaning. can you please help me?"Holy man smiled and replied, "Sure.."Man started telling him about his dream. He said, "In dream, I was being chased by a lion and while trying to save myself from lion, I climbed on a tree. lion sat down there, just below that tree waiting.there while sitting on branch, I saw that there were two rats circling around that branch of tree, eating it slowly. one of those rat was white and other was black.seeing that branch can fall of anytime soon. when again I looked down below, I saw that a snake was sitting right under my branch with his mouth wide open.when I looked around to see if there could be anything to hold on, I saw another branch with honeycomb on it and honey was dropping of that honey comb.seeing that I couldn't stop myself from tasting that honey and when I put my tongue out I got a drop of honey on my tongue and tasted that honey.even after tasting it once, I tried to get yet another drop of honey on my tongue and I got lost into it's sweetness and forgot all about those rats, snake and weak branch I was sitting on.just after that I woke up from my sleep.."Holy man listened to him carefully and replied, "Lion you saw in your dream was your death, it always chases you wherever you go..white and black rats represent day and night respectively. they circle around, coming one after another, to eat your time and take you closer to your death.the big black snake with a dark mouth that you saw is your grave. it's there, just waiting for you to fall into it.honeycomb you saw, represents this world, sweet homey you tasted were like luxuries of this world.when we come to this world, we like to taste luxuries of this world and once tasted, we want it again and again. meanwhile we get lost into it and forget about our time and death.." 
This world is like serpent, soft to touch but so full of lethal poison. Unwise people are allured by it and drawn towards it and wise men avoid it and keep away from its poisonous effects.
